I have prepared a patch to fix all the unchecked allocations.
Over the weekend I made some progress. To test the latest vendor driver, I installed a 32-bit system. Their driver is not compatible with a 64-bit system. I found that not only did the vendor driver work with secure sites, but so did the in-kernel version. I now have tcpdump output for the 32-bit case that works, and the 64-bit case that fails. It seems likely that I missed some 32/64 bit incompatibility when I did the conversion.
Thanks for all your help in trying to resolve this issue.
Larry
